With the foregoing i' ther objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts 'and in the details of construction hereinafter del scribed and' claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accornlpanying drawings, wherein :f-

Figure 1 is a plan view of an automobile vice in section.

Fig. 2 is an enlarged side elevation of the engine illustrating the air jackets in section.

Fig. 8 is a rear end view of the engine. j Fig. l is a sectional detail taken on 'the line 4- 4 of Fig. 2.n

The chassis illustrated in Fig. l'embodies a framel carried. by the steering wheels 2 and rea-r propelling wheels 3, and an electric motor 5% is carried by the frame and connected by-a shaft or other suitable connection 5 with the rear wheels through the Ine diuin of the usual ldicrential mechanism. The motor 1 is carried by a suitable transverse hanger 6 with which the frame 1 is provided between its ends. lrhe internal combustion engine is desighated generally by the referencecharacter 7, and includes a crank casing 8 and upstanding cylinders 9 of which theremay be and a plurality of engines can be used if desired. At one side of the engine 7 is an electric generator 10 nu'rcrrosrLn-Enernn.

loperated ,by the engine for supplying current to operate the motor 4, and through y' the medium of va suitable controller (not fsliown) 'the operation ofthe motor can be controlled to a nicety for providing ease and iexibility of operation.v A spur gear 11 is keyed to the crank shaft 12 of the engine and meshes withv an idler spur gear 13 which in' turn meshes with aspur gear '14 keyed upon the transverse shaft 15 of the generator 10, whereby to couple the generator to the engine.

Standards '16 of arch form are carried by the cylinders and other standards 16 at the ends, and said standards have bearings 17 for a longitudinal cam shaft` 18 that operates the intake and exhaustv valves in the heads of the cylinders, the dtails of which needr not be considered. A sprocket wheel 19 secured upon the shaft 18 near the forward end thereof is connected by an endless sprocket chain 20' with a sprocket Wheel 21 secured upon the same shaft as the idler gear 13, whereby the cam shaft 18 is operated when the crank shaft of the engine rotates.

The engine cylinders are air cooled, and for this purpose, an upright cylindrical air jacket 22 .or sheet metal or other suitable Y f spiermassa @fretta-s raient. Param-ed Jim@ r9, was,

niaterial surrounds each cylinder, and the jackets 22 are connected at their lower ends by connections 23, which with the lower ende of the jackets provide a discharge manifold for the air having an outlet 24: at the rear end yor at 'the rear side ofthe rear jacket 22 through which the heated air can be discharged. With the four cylinder engine illustrated, the jackets 22 are arranged in pairs for the two forward and two rear cylinders 9, and the forward and rear pairs of jackets 22 have their upper ends extending or curved angularly forward and rear- Wardly, respectively, and merging or united into funnels 25 of larger diameter than the ward the funnel. The portions 26 of the y two pairs of the two jackets serve to split the inlowing streams of air so that the air iows downwardly through the several jackets'22.

Air is forced into lthe tunnels 25 by means of rotary fans 27 mounted in the mouths thereof, and carried by suitable brackets 28 with which the unnels are provided. The fans 27 carry spur gears 29 which mesh with spur gears 30 secured upon the' ends of the c/am shaft" 18, in order that both fans will be operated when the crank shaft rotates.

The cylinders 9 are provided upon their peripheries within the air jackets 22 with spiral outstanding flanges 34 to give the downwardly owing streams of air whirling motions, to assistin the cooling action, and said flanges being cooled by the air will materially assist in cooling the 'walls of the cylinders.

If desired, the jackets 22 and their funnels 25 can be formed in two side sections secured together in any suitable manner, in order that the sections can be readily applied to and removed from the engine.

Having thus described the invention, what is claimed as new is 1.v An air cooling` device for engines embodying air jackets to inclose -the cylinders of amengine and united at one end to provide a discharge manifold for the air, the

other ends ofthe jackets extending angu- 4 larty and merging-into a funnel, the adjacent walls of the jackets being united by a portion curved toward said funnel for dividing the air.

2; The combination with-the cylinders of an engine, of air jackets inclosing them and united at one end to provide 'a discharge the funnel for dividing the air.

3. The combination with the cylinders of an engine, of air jackets inclosing-them and united at one end to provide a discharge -manifold for the air, the jackets being arranged in sets, the jackets o each set having. angularly extending portions at their other ends merging into a fu'nnel, the funnels of the two sets of jackets 'extending in opposite direct-lons, and fans rotatable within the mouths of the Ifunnelsv for forcing air into the same, from opposite directions Inv testimony that claim the Vforegoing as my own, I have hereto aixed my signature 1n the presence of two wltnesses.
